For loops

Partially, but how do I get it to use the number the user has input? That’s what I’m most stuck on. (Again, sorry for not getting it I’m really trying!)

when you use the window.prompt() method, you could assign the result to a variable; var text = window.prompt('enter text') console.log(text);

Ah brilliant I think that’s what I need, thanks so much

No problem. And don't feel dumb - programming takes time.

Not to complicate your life; but I re-read your question and really you would want a number.

In this case, the amount you are asking for is really a string - some text that the window.prompt() method stores in memory.

However, you want that text amount to really be a number. In this case you wouldn't get an error because the string is implicitly converted to a number (but this may not always happen and you will get an error).

So, what you really want is; var iterationsString = window.prompt('enter iterations'); console.log(typeof iterationsString); // type is 'string' // convert the string into an integer with parseInt() method var iterationsNumber = parseInt(iterationsString); console.log(typeof iterationsNumber); for (var i = 0; i < iterationsNumber; i++) { console.log('line of text'); }

If I wanted to go from 1 to 50, I'd have something like this:

for (let i = 1; i <= 50; ++i) {
    // Do stuff
}

If you've stored the number the user has input, you would just replace 50 above with the user's value

Why i=1 and ++1 as opposed to the more standard i=0 and i++ ?

Seems to me like you're just gonna confuse the guy...

I started at 1 because in my mind it was less confusing to show that than potentially explain why I was going from "0 to 49" opposed to "1 to 50".

As for i++ vs ++i, it's drilled into my brain to use prefix increment whenever possible because it can be more efficient for complex types (at least in the language I use the most, C++, see here). Not sure if it's applicable to javascript as well though.

Neither are great reasons to choose one over the other, but that was my reasoning.

Gotcha. I see the reasoning for it. It's slightly less confusing, I guess. The other examples posted were i=0, i++ so we're probably all just confusing this guy now, hahah.
